As rumoured, Apple has today updated its MacBook Pro line promising faster processors, NVIDIA graphics and longer battery life.

The 13-inch MacBook Pro now features the new NVIDIA GeForce 320M graphics processor for up to 80 per cent faster graphics and 10-hour built-in battery. With 48 processing cores, the NVIDIA GeForce 320M is billed as the fastest integrated graphics processor on the market.

Apple claims the 15-inch and 17-inch MacBook Pro laptops are up to 50 per cent faster. Using Intel’s 32 nanometer process, Intel Core i5 and i7 processors integrate the memory controller and Level 3 cache for faster access to system memory.

Hyper-Threading technology improves data throughput by creating virtual processing cores, while Turbo Boost optimises performance between the two processor cores, accelerating the system from 2.66 GHz to 3.06 GHz for intensive dual core tasks, and up to 3.33 GHz for single core tasks.

Apple notes, all 15-inch and 17-inch models include two graphics processors, the new NVIDIA GeForce GT 330M for peak performance and Intel HD Graphics for better energy efficient operation.

Apple adds, the MacBook Pro glass Multi-Touch trackpad now supports inertial scrolling, an intuitive way to scroll through large photo libraries, lengthy documents and long web sites. All MacBook Pros feature LED-backlit wide-angle displays with a broad colour gamut.

The 17-inch MacBook Pro includes a high resolution 1920 x 1200 display, while the 15-inch MacBook Pro is now available with an optional high resolution 1680 x 1050 display.

Customers can also upgrade their MacBook Pro with new 128GB, 256GB and 512GB solid state drives.
